The comparative analysis of the Russian chemical and manufacturing industry development per 2016–2024 is carrying out in the article. The characteristic features of the investments and innovations in the domestic chemistry, it’s historical prerequisite and actual specificity are identified
The branch structural research is undertaking. It’s staffing and means of production provision; dynamics of the manufactured products and the foreign economic supplies are exploring. The authors prove the growth of the chemical industry significance in the course of Russian import substitution and ensuring technological sovereignty.
The onset of chemical interaction between combustible gas components when the initial gas–air mixture is introduced into a dense bed of lump materials being blown through is preceded by a period of ignition with an increased temperature gradient between the lump materials and the gas molecules of the mixture, and an increase in the bed heating temperature to 800–1050°C. The increased adsorption activity of oxygen molecules on the solid surface of the bed reduces their concentration in the inter-lump space at the initial stage of the gas–air mixture movement, increasing the required air flow rate to 2.5–3.0. When supplying the initial gas streams directly into the fired bed of lump materials of varying particle sizes, two options are possible: supplying a prepared gas–air mixture, pre-mixed in special mixers, or supplying them in separate streams. Heat generation techniques create conditions for flexible control of the firing, sintering, and remelting technology of lump materials.
The Tula history of the gas chemical cluster forming based on JSC NSC «Azot» and JSC «Shchekinoazot» is research in the article. The further development prospects of the industrial cluster and the state support measures are evaluated. The authors suggest the direction of the interindustry cooperation for the regional gas chemical enterprises.
The tendencies of the industrial parks formation in the Russian agglomerations are considers in the article. The branch and territorial features of industrial parks foundation in the Tula region are determined on basis of the experience study of the special economic zone (SEZ) «Uzlovaya». The positive influence of the manufacturing SEZ on the branch clusters in agglomerations is confirmed.
